How to find the K max or min values contained in a vector?

Before I attempt to write the code myself, I was wondering if a function already exists to find the k max values of a vector.

E.g. test_vec = [ 5 9 8 3 2 1 7 6]; k = 3; [max_vals, max_ids] = max_elems(test_vec, k); max_vals = [ 9 8 7] max_ids = [2 3 7]

sort it 'descend' and extract the first k values.

I need the corresponding indices from the original vector per my example.

[max_vals, max_ids] = sort(test_vec, 'descend');

max_vals = max_vals(1:k);

max_ids = max_ids(1:k);
